Enzyme Kinetics & Catalysis

The quantitative study of enzyme-catalyzed reaction rates — Michaelis-Menten saturation kinetics, competitive and allosteric inhibition, temperature-dependent activity, and multi-substrate mechanisms that underpin all of metabolism.

Enzyme kinetics is the branch of biochemistry that measures how fast enzyme-catalyzed reactions proceed and how that rate depends on substrate concentration, inhibitors, temperature, and enzyme modifications. The foundational Michaelis-Menten model, published in 1913, revealed the hyperbolic relationship between substrate concentration and reaction velocity, introducing the concepts of Vmax and Km that remain central to pharmacology and biotechnology today.

These simulations let you explore the core models of enzyme catalysis: Michaelis-Menten saturation curves with Lineweaver-Burk linearization, competitive inhibitor dose-response, Hill equation cooperativity, Arrhenius activation energy with thermal denaturation, and multi-substrate ping-pong and sequential mechanisms. Adjust kinetic parameters and see how reaction velocities, inhibition curves, and mechanistic diagrams respond in real time.
